We are pleased to bring you the first release of EdgeTX Endeavour (2.4.0)!

In bringing you EdgeTX, our key goals for this first release were to:

• enable use of the touchscreen interface for color radios that support it
• allow use of high bit rate CRSF without having to modify your hardware if using transmitters like X9D+ and X7 via OneBit sampling mode

In bringing you EdgeTX, our main goal for this first release was to give to the community a usable touchscreen interface for color radios with touchscreens. Additionally, we wanted to establish a solid foundation for future features for the most commonly used radios.

We feel that we have now achieved these goals in a sufficient manner to warrant a release for wider use. EdgeTX releases are a "snapshot" of the current state of EdgeTX development, similar to a rolling release Linux distribution. As such, there will be some user interface / cosmetic issues, features not quite working as intended yet, or removed until they can be better implemented as part of the rewrite of the user interface that is under way.

As always with any new firmware version, regardless of who the publisher is, or if it is marked "stable" or otherwise, please ensure you appropriately bench test with a safe test rig before you use it out on the field. We endeavour to ensure that releases do not have any critical bugs that could compromise your ability to control your model (other than for any known issues or limitations, listed below), but as with any software, not every single possible combination and contingency can be catered for.

• Jumper T16 / T16 Plus / T16 Pro Hall
• Jumper T18 / T18 Lite / T18 Pro
• FrSky X10 / X10S / X10 Express / X10S Express
• FrSky X12S / X12S-IRSM

Limitations and Known Issues

The current release has the following limitations:

• You are not (yet!) able to import or edit EdgeTX models using OpenTX Companion (but firmware flashing with OpenTX Companion is still possible). Your OpenTX models and settings will be automatically converted by EdgeTX, and changes to model and radio settings will need to be done on the radio until the Companion software is updated to suit. Work is progressing on updating Companion to support the changes in EdgeTX.
• Panels / widgets will not be preserved in the conversion from OTX 2.3.x => ETX 2.4 on color screen radios due to incompatibility in how the settings were stored (OTX2.3 does not include the type of the options in the binary file). This is a one-time issue.
• You are not yet able to move models between categories, or create/edit categories via the user interface. However, you can edit the /RADIO/models.txt in order to do this manually). In the future, we hope to implement favourites support, as well as flexible labeling/tagging system.
• You are not able to select a theme or modify the default theme color scheme. However, you can change the splash screen and background image in the traditional manner (/IMAGES/splash.png and /THEMES/EdgeTX/background.png).
